Description

Technical Field

[0001] This invention relates to the field of sanitary product testing technology, and in particular to an apparatus for testing the cleaning effect of sanitary products on the anal area. Background Technology

[0002] As people's living standards improve, new cleaning products such as toilet wipes and wet toilet paper are becoming increasingly popular. Compared to traditional dry toilet paper, their differences in cleaning performance and comfort have attracted widespread attention from consumers and manufacturers. The difference in cleaning performance between wet and dry toilet paper is affected by a variety of factors, including the type and adhesion characteristics of the dirt, the amount and location of the dirt, the properties of the test substrate, the wiping path and force, and the observation conditions and judgment methods. Therefore, a standardized evaluation device and method are needed to scientifically and fairly compare and evaluate the cleaning effects of different wiping substrates, providing a basis for product development, quality control, and market promotion.

[0003] The current common evaluation methods in the industry have the following shortcomings:

[0004] Lack of consistency in contamination loading: Common practices rely on manual smearing or dripping of simulated contaminants, which makes it difficult to ensure that the volume, location and distribution of each loading are consistent, resulting in poor comparability of test results from different batches and different operators;

[0005] Insufficient biomimicry: Some evaluations use flat substrates or simple curved test carriers, which cannot reflect the actual wiping difficulties caused by the local curvature, wrinkles and depressions of the perianal area, and the test results are out of touch with the actual use scenario;

[0006] Inconsistent judgment criteria: Residue after wiping is usually observed with the naked eye, which is easily affected by ambient light intensity, observation angle, observation distance and operator subjective differences, resulting in high dispersion of judgment results;

[0007] The indicator system is incomplete: some evaluations only focus on the final residue and lack a comprehensive characterization of wiping efficiency (the number of times required to achieve cleaning) and substrate integrity (the risk of damage during wiping), which cannot fully reflect the overall performance of the product.

[0008] To address the aforementioned issues, there is an urgent need for a testing device that can simulate quantitative loading of contaminants, has a high degree of biomimicry, and facilitates standardized observation conditions, in order to improve the repeatability and comparability of the cleaning effect evaluation of different wiping substrates. Summary of the Invention

[0009] The purpose of this invention is to provide a device for testing the cleaning effect of sanitary products on the anal area, so as to solve the problems of poor consistency of simulated dirt loading, insufficient biomimicry of the test carrier, and inconsistent observation conditions in the prior art.

[0010] The technical solution of the present invention is as follows: A device for testing the cleaning effect of sanitary products on the anal area includes:

[0011] Box body;

[0012] The biomimetic model module includes at least two biomimetic buttock models disposed on the top of the box body. The biomimetic buttock models are made of transparent and elastic material. Each biomimetic buttock model includes a simulated anal region. Each biomimetic buttock model has a conduit embedded inside, and the outlet of the conduit is located in the simulated anal region of the corresponding biomimetic buttock model.

[0013] The conveying module includes a simulated waste container, a conveying pipe, a peristaltic pump assembly, and a dispensing module. The inlet of the conveying pipe is connected to the interior of the simulated waste container, and the outlet of the conveying pipe is connected to the dispensing module. The outlet of the dispensing module is connected to at least two of the aforementioned conduits. The peristaltic pump assembly is disposed on the conveying pipe to drive the quantitative conveying of simulated waste.

[0014] The transmissivity enhancement module is used to enhance the transmissivity or reflection display effect of the simulated anal area corresponding to the bionic buttock model, so as to improve the visibility of simulated dirt residue.

[0015] Based on the above scheme, the following improvements are made: the light enhancement module includes a light source located at the bottom or below the bionic buttock model.

[0016] Based on the above scheme, the following improvements are made: the light enhancement module includes fluorescent powder or reflective powder uniformly dispersed in the bionic buttock model, which, in conjunction with light irradiation, enhances the visibility of simulated dirt residue.

[0017] Based on the above scheme, further improvements are made as follows: a wiping mechanism is installed on the box body. The wiping mechanism includes a wiping motor, a rotating arm, a connecting rod, and wiping springs. The wiping motor drives the rotating arm to rotate, and the rotating arm drives the connecting rod to rotate. The wiping springs are set one-to-one with the simulated anal area of ​​the bionic buttock model, and each wiping spring is installed side by side on the connecting rod. The lower end of the wiping spring is provided with a wiping head, which is an elastic ball for installing the sanitary products to be tested.

[0018] Based on the above solution, the following improvements are made: the wiping head is equipped with an elastic clip to clamp and fix the sanitary products to be tested.

[0019] Based on the above solution, the following improvements are made: the wiping spring has a corrugated structure.

[0020] Based on the above scheme, the following improvements are made: the box body is equipped with a waste mixing module, which includes a mixing container, a stirring mechanism, and a feeding mechanism. The stirring mechanism is located in the mixing container, and the feeding mechanism is used to add materials to the mixing container to mix different types of simulated waste.

[0021] Based on the above scheme, the following improvements are made: the allocation module is a Y-type allocation module or a T-type allocation module.

[0022] The beneficial effects of this application are as follows: When using the device for testing the cleaning effect of sanitary products on wiping the anal area, the prepared simulated waste is poured into the simulated waste container, the delivery tube is connected to the simulated waste container, the power switch is turned on, and the peristaltic pump component of the system control delivery module is started, so that the simulated waste in the simulated waste container is sucked into the delivery tube. After being equally distributed by the distribution module, it flows through each conduit to the simulated anal area of ​​the corresponding bionic buttock model. The peristaltic pump component is started at the same time each time to ensure that the amount of simulated waste pumped each time is the same, and the simulated waste always comes out from the anus, which ensures that the simulated waste is in a consistent position. Then, the simulated anal area of ​​at least one bionic buttock model is wiped manually or mechanically with wet toilet paper and dry toilet paper respectively. After the transillumination enhancement module is activated, the bionic buttock model is transilluminated so that the waste residue can be observed more clearly. As can be seen, compared with the prior art, this application can achieve quantitative loading of simulated dirt through a peristaltic pump assembly and a dispensing module. A biomimetic buttock model made of transparent and elastic material simulates the real human anal area, including the anus and surrounding folds and depressions. The transillumination enhancement module, in conjunction with the transparent material, enhances the display of the wiping effect, making the details clearer. Furthermore, since the brightness of the transillumination enhancement module is uniform, it can reduce the impact of changes in ambient light on the observation results after wiping and improve the consistency of observation conditions.

[0023] Furthermore, by designing a wiping mechanism, mechanical methods are used to replace manual wiping, ensuring that the force, angle, direction, and length of each wipe are consistent. This avoids the influence of human error, as manual operation relies on experience and physical condition, making it difficult to guarantee consistency in force, path, and angle each time. Moreover, since the wiping springs are all connected to the same linkage, each wipe is performed synchronously, minimizing variable interference and improving the accuracy of the wiping test. The elasticity of the wiping springs and wiping head can adapt to the contact and contact force with the surface to be wiped, and can also simulate the force variations experienced during actual manual wiping.

[0024] Furthermore, the inclusion of a waste preparation module can improve the versatility and realism of simulated waste. This is because real perianal waste (such as feces) varies greatly in morphology (solid / semi-solid), viscosity, and composition (containing fiber / moisture). A single simulated substance cannot cover the cleaning effect evaluation of different scenarios. The waste preparation module of this application can adjust various parameters of simulated waste, such as viscosity, consistency, fiber content, and particle size. Attached Figure Description

[0035] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0036] Specific embodiments of the apparatus of the present invention for testing the cleaning effect of sanitary products on wiping the anal area: as follows Figures 1-6 As shown, the device for testing the cleaning effect of sanitary products on wiping the anal area includes a box 1, a mobile power supply 10, a control switch, a biomimetic model module, a conveying module, a transillumination enhancement module, a wiping mechanism 9, and a waste mixing module.

[0037] Box 1 is a square box with an internal cavity. The side wall of box 1 has a power supply hole, a self-locking switch hole, and a speed control potentiometer hole for installing or bringing out the power interface, self-locking switch, and speed control potentiometer. The power interface, self-locking switch, and speed control potentiometer are electrically connected to the driver board for power supply, start / stop, and speed control.

[0038] The bionic model module includes at least two bionic buttock models 2 disposed on the top of the box 1. The bionic buttock models 2 are made of a transparent and elastic material, preferably a transparent low-hardness silicone material. The bionic buttock models 2 include a simulated anal region 21. Each bionic buttock model 2 has a conduit 3 pre-embedded inside, and the outlet of the conduit 3 is located in the simulated anal region 21 of the corresponding bionic buttock model 2.

[0039] The conveying module includes a simulated waste container 4, a conveying pipe 5, a peristaltic pump assembly 6, and a distribution module 7. The inlet of the conveying pipe 5 communicates with the interior of the simulated waste container 4, and the outlet of the conveying pipe 5 connects to the distribution module 7. The outlet of the distribution module 7 connects to at least two of the aforementioned conduits 3. The peristaltic pump assembly 6 is mounted on the conveying pipe 5 to drive the quantitative conveying of simulated waste. The conveying module is housed within the receiving space of the housing. The distribution module 7 can employ a Y-type distributor, a T-type distributor, a manifold, or other equal-volume distribution structure. The peristaltic pump assembly 6 can be a motor-driven peristaltic pump structure.

[0040] A transmissive enhancement module is disposed at the bottom or below the bionic buttock model 2, and includes at least one high-brightness light source 8, preferably a high-brightness LED spotlight, for transmissive illumination of the transparent silicone bionic buttock model 2 to enhance the visual contrast of simulated dirt residue. In a preferred embodiment, the high-brightness light source is an LED light source.

[0041] A wiping mechanism 9 is installed on the housing 1. The wiping mechanism 9 includes a wiping motor 91, a rotating arm 92, a connecting rod 93, and wiping springs 94. The wiping motor 91 drives the rotating arm 92 to rotate, and the rotating arm 92 drives the connecting rod 93 to rotate. The wiping springs 94 are arranged one-to-one with the simulated anal area 21 of the bionic buttock model 2, and each wiping spring 94 is mounted side by side on the connecting rod 93. The lower end of the wiping spring 94 is provided with a wiping head 95, which is an elastic ball for attaching the sanitary product to be tested. The wiping head 95 is provided with an elastic clip for clamping and fixing the sanitary product to be tested. The wiping springs 94 have a corrugated structure. By using the wiping mechanism 9, mechanical methods are used to replace manual wiping, ensuring that the force, angle, direction, and length of each wipe are consistent. This avoids the influence of human error, as manual operation relies on experience and physical condition, making it difficult to guarantee consistency in force, path, and angle each time. Furthermore, since all wiping springs 94 are connected to the same connecting rod 93, each wipe is performed synchronously, minimizing variable interference and improving the accuracy of the wiping test. The elasticity of the wiping springs 94 and the wiping head 95 can adapt to the contact and contact force with the surface to be wiped, and can also simulate the force changes during real manual wiping.

[0042] The box body 1 is equipped with a waste mixing module, which includes a mixing container, a stirring mechanism, and a feeding mechanism. The stirring mechanism is located in the mixing container, and the feeding mechanism is used to add materials to the mixing container to mix different types of simulated waste. The waste mixing module can improve the versatility and realism of simulated waste because real perianal waste (such as feces) varies greatly in morphology (solid / semi-solid), viscosity, and composition (containing fiber / moisture). A single simulated substance cannot cover the cleaning effect evaluation of different scenarios. The waste mixing module of this application can realize the mixing of various parameters of simulated waste, such as viscosity, consistency, fiber content, and particle size.

[0043] When using the device for testing the cleaning effect of sanitary products on the anal area, the prepared simulated waste is poured into the simulated waste container 4, the delivery pipe 5 is connected to the simulated waste container 4, the power switch is turned on, and the peristaltic pump assembly 6 of the system control delivery module is started, so that the simulated waste in the simulated waste container 4 is sucked into the delivery pipe 5. After being equally distributed by the distribution module 7, it flows through each conduit 3 to the simulated anal area 21 of the corresponding bionic buttock model 2. The peristaltic pump assembly 6 is started at the same time each time to ensure that the amount of simulated waste pumped is the same each time, and the simulated waste always comes out from the anus, which ensures that the position of the simulated waste is also consistent. Then, the simulated anal area of ​​at least one bionic buttock model 2 is wiped manually or mechanically with wet toilet paper and dry toilet paper respectively. As can be seen, compared with the prior art, this application can achieve quantitative loading of simulated dirt by using the peristaltic pump component 6 and the distribution module 7. The biomimetic buttock model 2 made of silicone material simulates the real human anal area, including the anus and surrounding folds and depressions. The transillumination enhancement module, together with the transparent silicone material, enhances the display of the wiping effect, making the details clearer. Moreover, since the brightness of the transillumination enhancement module is uniform, it can reduce the influence of changes in ambient light on the observation results after wiping and improve the consistency of observation conditions.

[0044] In other embodiments, the transillumination enhancement module can also employ a non-light source approach, such as doping the silicone of the biomimetic buttock model with uniformly dispersed phosphors or other fluorescent substances, thereby enhancing recognizability during testing by irradiating the material with light in advance. Alternatively, the phosphors or fluorescent substances can be replaced with reflective powders or reflective substances to enhance the visibility of residue in the simulated anal area through reflection.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
